Environmental Compliance has developed the ESP systems with automation simplicity and cost considerations as the two top design characteristics. The ESP systems are available in a variety of ``gallon per batch`` sizes to fit almost any application. These units can also be ganged together to meet the in between needs.
ESP Systems
Each ESP system is controlled using the popular Allen Bradley ``micro logic`` PLC. The ease in operating these units compared to other systems on the market can only be characterized as plain simple. The investment in the technology is also much less than you will find. Environmental Compliance also developed the ``FS Series`` of ``portable`` ``semi-automatic`` units for smaller operations where the need for waste water treatment is usually once a week or even once a month. Environmental Compliance utilizes only the best technology to get the job done right. These systems were voted ``Best Technology in 2000`` by CleanTech readers. Environmental Compliances encapsulation services and solutions include:
- FS UNITS
- 10 GPB
- 250 GPB
- 400 GPB
- 600 GPB
Chromium Destruction System
ESP 600 is available with a chromium destruction system addition. This equipment combination will first reduce Chrome6 to the trivalent form and transfer the solution to the ESP unit for further treatment through encapsulation, automatically. The units communicate to determine the others conditions to provide a continuous operation with no cross contamination. The chrome reduction system (CR1) can be a stand alone operation. This combination is available on all ESP models.
Environmental Compliance places great importance on the role of ECE CLAYFLOC based products in wastewater treatment. Clay is a proven part of wastewater treatment. Typically, industrial wastewater may be contaminated with suspended solids, heavy metals, organic compounds and other potential pollutants. Various methods exist for removal of these contaminants, to include acidifying (to break oil emulsions) precipitating heavy metals, adding primary coagulants, coagulant aids, settling, filtration etc. In general, a series of steps is necessary, requiring the addition of various chemicals to several mixing tanks and equipment. The resulting sludge produced, depending upon the initial contaminants, may be classified as hazardous, entailing high disposal costs.
ECE Clayfloc lines of products are highly efficient wastewater treatment formulations that are designed to be mixed in a dry state directly to a contaminated industrial wastewater. The products are dry powders comprising a blend of sodium montrmorillonite clay, pH adjusting items and polymers (polyelectrolytes). The various ingredients act in a sequential fashion to break oil and water emulsions, precipitate heavy metals as hydroxides, promote flocculation, agglomeration and suspended solids removal. ECE Clayfloc formulations are directly applied to a waste stream; clay particles flocculate, removing certain cationic metal contaminants from solution.
In the few thousand years that followed, the noncrystalline material organized itself into very small crystalline units that in time developed into a waxy claylike substance. Eventually a massive uplift of the seafloor occurred, forming what we know today as the Bighorn Mountains. As a result of millions of years of erosion, the bentonite deposits have outcropped on the surface and are recognized as narrow, light colored bands running parallel to the mountains. This unique product of nature`s forces called bentonite can be classified as sodium based montmorillonite clay. Nowhere else but in the confines of North West U.S. is this clay mineral found in such quantity and with such consistent properties. Bentonite structurally is made up of billions of tiny plate-like particles, each averaging less than 1 micron in size (1 micron is about 1/25,000 inch) These particles are staked or layered one upon the other, much like sheets of paper in a tablet. If one could separate platelet from its neighbor and place them side by side, approximately one handful of bentonite (or one cubic inch) would more than completely cover a half acre of land.
Bentonite`s unique molecular structure, which allows it to absorb nearly five times its weight in water and swell to a volume of 12 to 16 times its dry bulk are very significant factors to consider when we begin to assess its applications for industrial wastewater. As mentioned earlier, clays, and bentonite in particular, are hydrous aluminum silicates. The bentonites are composed of three layers of silicates compressed into a microscopic sized plate sandwich. Despite their small size however, the platelets have a relatively large surface area. The edges of the bentonite platelets are positively charged and the flat surface areas of the platelets are negatively charged. Because of their small size, electrostatic charges control the bentonite platelet behavior, and they are strongly attracted or repelled by each other and various other substances as well.
Recent cost analysis has shown that by using ECE Clayfloc clay-based products for wastewater treatment, users could expect to save 80-90% over conventional waste transport and disposal costs, making this alternative not only efficient, but also cost effective. Many variables are to be considered when weighing options for wastewater treatment such as volumes of water to be treated, waste constituents, and equipment necessities. However, clay-based products have proven to be a viable alternative to wastewater treatment.
