PACT Multi-Media and Self Cleaning Filters (MMF and SCF)
The PACT MMF uses several layers of proprietary media installed in vertical or horizontal pressure vessels. The media require occasional backwash, achieved automatically or manually. The PACT SCF is a self-cleaning screen-based filter in a pressure vessel that automatically flushes itself upon a pre-set pressure loss. Both types of filters have their applications. The PACT MMF and SCF are employed both as pretreatment and post-treatment.
PACT Ultraviolet (UV)
Ultraviolet disinfects waste water by damaging the DNA and RNA of microorganisms such as salmonella, giardia, microscopic worms and viruses. PACT UV systems can have lowpressure or medium-pressure lamps. Medium-pressure lamps are normally used at large treatment facilities. The effective UV dose is dependent primarily on the combined effects of the UV light intensity, the exposure time and the UVT (ultraviolet transmittance). UV Transmission varies over time and from site to site as it is related to the quantity of organics, colloidal solids and other material in the water, which absorb and scatter the UV light as it passes through water.
PACT Ozonation (OZ)
The PACT OZ is used as a disinfectant in water as well as an oxidizer for COD removal in wastewater. The PACT OZ consists of an ozone generator, catalytic or thermal ozone destructor, oil less compressor and dryer, titanium diffuser, air or water cooled chiller, programmable logic controller, dewpoint/oxygen/ozone analyzers, oxygen/ozone leak detectors, temperature and pressure indicators, all mounted as a compact unit on a high alloy steel skid.
PACT Ballast Water Treatment (BWT)
The PACT BWT a ship-deployed system consists of two main treatment steps that of filtration (PACT SCF) and disinfection (PACT UV). The ballast water is treated at seawater intake (ballasting) and again at ballast water discharge (de-ballasting). During ballasting, water is processed through both the filter and UV stages as it is pumped from sea chest to the ballast tanks. At any one time some 7,000 different species are being carried in ships’ ballast tanks, and when discharged many of these organisms have the potential to create disastrous biological invasions with serious ecological, economic and public health consequences.
PACT Dissolved Air Flotation (DAF)
The PACT DAF is typically used in the food and chemical processing facilities, pulp and paper processing, and any facility, which requires the reduction of oils, fibers, and other light solids. PACT with its superior small bubble air-diffusion is well suited for the removal of suspended light solids such as oil, fibers, proteins, starches, blood, inks, dyes and other substances that do not settle through gravity.
PACT Mechanical Sludge Dewatering (MSD)
PACT MSD machines for municipal and industrial water and wastewater dewatering are backed by expert process engineering support, and over 30 years of experience in the industry. Depending on type of sludge to be dewatered, PACT recommends one of several dewatering mechanisms it supplies, namely filter press, belt press or centrifuge. All critical parts (motors, variable drives, bearings, solenoids, pistons, limit switches, E&C, instrumentation, etc.) are sourced from globally reputable name brands.
PACT Pump Station Packages (PSP)
PACT designs and builds pumping packages complete with all interconnecting piping, valves, instrumentation and control panel. PACT PSP packages are used in municipal water and sewage treatment plants as well as re-pressurization and firefighting. PACT controls and supervises the pumping stations through the use of a programmable logic controller (PLC) or remote terminal unit (RTU). RTUs are very helpful in remote monitoring of each pumping station from a centralized control room with SCADA (Supervisory Control & Data Acquisition) systems. This setup can be helpful in monitoring pump faults, levels or any other alarms and parameters making it more efficient.
