Having the best oil sludge processing centrifuge is only part of the HydroPure STS. In order to allow the centrifuge to efficiently process oily waste sludge, HydroPure has developed a chemical treatment program that is tailored to treat the waste generator's sludge. To illustrate the necessity of a chemical treatment program, centrifuges are similar to laundry washing machines in that they cannot perform their task without help from surface active agents (surfactants). The best washing machine ever built cannot function without detergent. Similarly, the HydroPure Tri-Phase Centrifuge or any other centrifuge cannot process oil sludge without the proper chemical program to neutralize the binding forces within the sludge.

The HydroPure PetroChem chemical treatment system was developed to address the problems associated with processing the most difficult sludges. HydroPure has successfully separated sludges containing high concentrations of fine clay, iron sulfides, organic chlorides and other difficult to remove substances. Sludge processed through the HydroPure STS is regularly separated into 99.5% or greater oil purity while discharging dry solids and clear water in the other two phases.

The HydroPure PetroChem chemical treatment program consists of high grade flocculating polymers, detergents, demulsifiers, and other surfactants specially formulated to effectively and economically separate oil sludges. Although the HydroPure PetroChem treatment program is the most effective chemical treatments available for treating oil sludges, the cost is usually less than the inferior products offered by major petroleum chemical manufacturing companies.

Although the HydroPure PetroChem chemical treatments were formulated to work with a centrifuge system, they have been proven effective and economical in other types of separation devices such as coalescers, presses, filters, and settling tanks. In addition to providing chemical treatments to the petroleum and environmental industries, HydroPure is also capable of formulating a chemical treatment program in any industry which has the need to separate mixtures containing liquids and solids.
