Hydrokleen Wastewater Recycling & Pre-Treatment Systems

Hydro Engineering, Inc. has been supplying bio-mechanical filtration systems for equipment and vehicle washing applications since 1986. We are experts at determining what will work for your application.

Hydrokleen™ filtration and recycling equipment are modular in design. Determine what you need, based on your effluent and discharge or recycling requirements, and get just those components.

Whether you need solids settling, solids filtration, oil coalescing and skimming, bioreactors, emulsified oil filtration, heavy metals filtration, you choose the module to fit your application.

We have highly trained Project Managers that can assist you with your requirements for water filtration or recycling.

Hydrokleen Solids/Liquid Separation

When using Hydropad portable wash rack systems where in-ground water storage is minimized, our SST is the answer. Why put the water storage below ground and settle out solids there? The SST is self cleaning. SST Solids Settling Tank


Bioreactors

Bioreactors can accomplish tasks that mechanical filtration cannot. Organic chemicals will pass right through any mechanical filtration system, although particulate matter can be removed. With a Bioreactor we can break down and consume hydrocarbons and organic chemicals found in many waste streams. Our Bio-Mechanical approach allows our systems to do what the others cannot....

pH Monitoring and Dosing Systems

By using a pH monitor, you can determine the exact pH levels of solutions. For example, rather than say that lemon juice is quite acidic, you can say that lemon juice has a pH of 2.4. An exact pH value can be used to control and/or measure acidity or alkalinity levels in your Hydrokleen water filtration and recycling equipment. The pH monitor can automatically dose counteracting chemical(s) into the wastewater to make a change in the pH.

Sump Cleaning Made Easy

Our Sump Sucker And Sludge Cart Can Be Used With Hydropads
With these two inexpensive items you can now clean your own sumps. That's right--no more calling the pumper truck and paying high hauling fees. If your wastewater treatment system is using our Hydro-Biodigesters, chances are the sludge you remove is land fill acceptable. Our Biodigesters eat the oils, grease and hydrocarbons from the sludge. Disposal becomes cheap and most customers can put it straight into their dumpster. Check your local regulations first.

Unique In-Ground Sump w/Separator

This 3 x 3 x 4' deep all-steel sump has a unique solids separation basket.
Rocks collected in the basket are easily dumped out by tilting the hinged basket 90 degrees. It's all welded steel construction with epoxy coating to insure durability beyond what pre-cast, plastic or fiberglass sumps offer.
