Typical Violations

Improper Surface Cleaning

·       Our proprietary power washing the rotor equipment removes dirt and chemical contaminants from restaurant exterior, patio, surrounding pavement and parking lot.
Water reclaimation process collects, processes and recycles water.

Improper Waste Storage Area Management
Waste storage areas are receptacles for pollutants, dangerous chemicals, mold and bacteria. These areas are often forgotten and become a deterrent to customers and hazardous to the environment. We specialize in cleaning and sterilizing dumpsters and the waste storage areas around them.

Pesticides and other contaminants
Our water reclaimation system prevents pesticides, cleaning agents and and other contaminants from being washed down the storm drain.

Improper Furniture Cleaning
Our cleaning agents and washing system is gentle on your restaurant furniture, and ensures that any potential pollutants are removed and processed.

Patio and Sidewalk Cleaning
Your patio dining area and sidewalks can collect chemical residue and food materials that cannot be washed down storm drains.  Our machinery picks up debris from patios and sidewalks, leaving your dining area redy for new patrons and your storm water clear of hazardous materials.

Service Providers
You are responsible for the compliance of your service providers (i.e. grease haulers, trash collectors, and pressure washers).

Araya Clean is a proud provider of environmentally safe and compliant procedures.

Did You Know Property Owners Are Responsible For Proper Waste Water Disposal?

Whenever there is wastewater discharging from a pipe or other “point” source into a storm drain, you will be subject to the Clean Water Act’s National Pollution Discharge Elimination System.
 

Section 301 of the Clean Water Act (CWA) prohibits a point source discharge of pollutants.
 

Penalties and fines vary but can be as high as $50,000 each day of non compliance. The most common method of compliance with the CWA is to prevent process waste water discharges.

Araya Clean utilizes a 5 stage recycling filtration system. This system captures the waste water runoff and the reclaimed runoff is vacuum pumped to our filtration system. Contaminants are captured and the processed water is re-used in the cleaning process.

The Araya Clean System complies with the EPA Clean Water Act so it protects you from potential fines, penalties and legal action. Since the Araya Clean System reclaims, filters and reuses the waste water it reduces water consumption which saves you money and is good for the environment at the same time.

Home-use pressure washer powered by a small gasoline engine
A pressure washer is a high pressure mechanical sprayer that can be used to remove loose paint, mold, grime, dust, mud, and dirt from surfaces and objects such as buildings, vehicles, concrete surfaces, etc. The volume of a pressure washer is expressed in either gallons or litres per minute, often designed into the pump and not variable. A pump's pressure, expressed in pounds per square inch, pascals, or bars (depreciated), is also designed into the pump but can be varied by adjusting the unloader valve. Machines that produce pressures from 750 to 30,000 psi (5 to 200 MPa) or more are available.
The basic pressure washer consists of:
Similarly as a garden hose nozzle is used to increase the velocity of the liquid, a pressure washer adds its own power to create high pressure and velocity. The pump cannot draw more water from the pipe to which the washer is connected than that source can provide. Moreover, the water supply must be adequate for a given machine connected to it, as water starvation leads to cavitation damage of the pump elements.
Several different types of nozzles are available, each useful for a particular application. Some nozzles cause the water jet to be ejected in a triangular plane (fan pattern), while others emit a thin jet of water, which spirals around rapidly (cone pattern). Nozzles that deliver a higher flow rate lower the output pressure. Most nozzles attach directly to the trigger gun.
Some pressure washers, in combination with a particular nozzle, allow detergent to be introduced into the water stream, assisting in the cleaning process. Two types of chemical injectors are available — a high-pressure injector that introduces the chemical after the water leaves the pump (a downstream injector) and a low-pressure injector that introduces the chemical before water enters the pump (an upstream injector). The type of injector used is related to the type of detergent used, as there are many chemicals that will damage a pump if an upstream injector is used.
Pressure washers are dangerous tools and should be operated with due regard to safety instructions. The water pressure near the nozzle is powerful enough to strip flesh from bone. Particles in the water supply are ejected from the nozzle at great velocities. The cleaning process can propel objects dislodged from the surface being cleaned, also at great velocities. Pressure washers have a tendency to break up tarmac if aimed directly at it, due to high pressure water entering cracks and voids in the surface.
Most readily available consumer units, commonly found online or at hardware stores, are electric- or petrol-powered. The electric ones plug into a normal outlet, use cold tap water and typically deliver pressure up to about 2,000 psi (140 bar). Petrol powered units can often deliver twice that pressure, but due to the hazardous nature of the engine exhaust, they are unsuitable for enclosed or indoor areas. Some models can generate hot water, which can be ideal for loosening and removing oil and grease.

Origin

The first hot-water high-pressure washer was invented by Alfred Kärcher in 1950.[1] However, Frank Ofeldt in the United States claimed to have invented the steam pressure washer or "high-pressure Jenny" much earlier, in 1927.[2][3]

Uses

In its extreme high pressure form, water is used in many industrial cleaning applications requiring the removal of surface layers as well as dust-free cutting of some metals and concrete. For exterior applications, gas or propane powered pressure washers provide enhanced mobility not available in electric models, as they do not require use in proximity to an electrical outlet. However, for indoor applications, electric pressure washers produce no exhaust and are much quieter than their gas or propane powered counterparts.
High-pressure water at medium pressure, in combination with special chemicals, aids in the removal of graffiti. This process (especially when the water is hot) is used as a quick rinser of the softened graffiti. Sometimes people use a pressurized mixture of air/sand or water/sand to blast off the surface of the vandalized area, thus etching the surface and therefore making it extremely difficult for anyone to ever use high-pressure cleaning as a follow-up process. Sandblasting, when used in graffiti removals, often overcleans a surface and is capable of leaving a permanent scar on the building surface.

Types

Pressure washers are classified into following groups based on the type of fuel/energy they consume.
  • Electric pressure washer
  • Diesel pressure washer
  • Petrol pressure washer
  • Gas pressure washer
  • Ultra high pressure washer
  • Hydraulic high pressure washer
  • High pressure steam cleaner

Specialty washers

An insulator pressure washer[4] is a mechanical high pressure washer designed to remove contamination/pollution from overhead power line insulators using low conductivity water with the power on (energized). Cleaning is necessary to prevent flashovers (high voltage shorts to earth across the insulators) which can damage power line equipment.[5]

Truck Chassis Mount Insulator Washer Unit
The basic design[6] consists of the following components:
  • A Power Source (a diesel engine or a Power Take Off from a truck chassis)
  • A centrifugal water pump
  • A stainless steel water storage tank
  • A high pressure water hose
  • A high pressure dead-man type water wash gun
  • Electrical grounds for the wash gun and washing system
Insulator washers typically have a pump pressure of about 1000 PSI and a nozzle pressure between 500 - 750 psi. They have a very high flow rate (about 60 gallons per minute) The high flow rate is necessary to provide consistent and fast cleaning of the insulators.
Insulator washers have several basic design layouts [7] as follows:
  • Trailer mount for use in electricity substations [8]
  • Chassis mount for mounting on a truck bed [9]
  • Aerial platform mount for mounting on trucks that have aerial platforms
  • Helicopter mounted units [10]
The washing unit must be able to access the electric towers to be washed. If the towers are off road in rough terrain, a 4x4, 6x4 or even 6x6 truck chassis may be required.
The systems must have a robust design as they are used outdoors, often in adverse climates.
