Biofiltration system in livestock industry
Cattle wastewater obtains from washing the milking place of the cattle and the breasts of the cow before and after milking. The collected sewage has an average COD of 4000, milk residues and excrements and it can be considered as one of the polluting industries, so the treatment of cattle waste is one of the priorities of every cattle farm. PGA biofiltration system is capable of purifying this kind of waste to COD less than 100 and can be used in agriculture. PGA biofiltration system in livestock with the capacity of 50 m^3 per day can be installed in 20 foot container and transport to the cattle farm. In the Picture below, there is an installed PGA biofiltration system in cattle farm.
Desalination with reverse osmosis method
Water purification and desalination system with reverse osmosis method
The process of reverse osmosis or water sweetening is a method to separate impurities from water. In this method, the separation factor is mechanical pressure. Currently, the reverse osmosis process plays a very important role in water purification.
Filters (sand, carbon, micron and disk)
Usually, a sand filter is used to remove all kinds of physical and biological suspended particles in water up to 50 microns in diameter. This impurities can include any types of organic materials, planktons, bacteria and particles of rust, mud and dyes.
Food industry wastewater treatment system
Various food industries including production factories such as dairy products, canned food, compote, tomato paste, juice, soft drinks, dry beans and ready-to-eat vegetable, despite the wide variety of products, have similar quality in waste production. The amount of COD and BOD of this industries are in 100-10000 milligram per liter.
Grey water treatment and recovery system
Grey water treatment and recovery system
Grey water includes water obtained from washing the sink, laundry, bathroom etc. except for heavy human waste. Residential units, businesses, hotels and public places, industrial washing workshops such as car washes, carpet cleaners, factories for washing and packing food, dry fruits and vegetables are among the uses of this type of biofilter. The water obtained from the purification can be used for washing the yard and car, watering plants, supplying flash tanks and also for industrial applications.
Hydro cyclone
A simple and effective tool for removing abrasive grains and solids from water. Due to its high efficiency (95 percent) in removing particles, ease of installation and use, and reasonable price, this device has a special place in water purification and water supply systems. If the working conditions and pressure are favorable, it can remove particles up to 75 microns.
leachate treatment system
Garbage leachate is a fluid obtained from buried or recycled garbage which has various dangerous and toxic substances and in according to geographic region, has different range from 10000 to 120000 in BOD, COD and TDS and in case entering to environment has irreversible effects and must be treated. Here in PGA company, we have succeeded in setting up a waste water treatment system based on biofilter. One of this system successfully installed in garbage collection stations of Tehran. That has capacity up to 20 cubic meters per day and can install a 20 foot mobile-container, picture of this system is given bellow.
Resin water softener system
Resin softener (mechanical softener or ion-exchange softener) is the most common softener in market, which reduces hardness of water by reducing calcium and magnesium; usually are used for industrial, residential and business uses.
Wastewater treatment system for leather industries
Biofilter system in leather industry
Leather industries have high water consumption so they release enormous wastewater in environment, and usually have high amount of BOD, COD, TDS, sulfide, ammonium, nitrate and heavy metals such as chrome, industrial salts, organic compounds and skin waste. In case that this waste enters into the environment without treatment, it causes severe damage to the environment. PGA biofiltration, using a combination system physical, chemical and biological methods based on biofilter is capable of purifying of sewage of leather industry up to the standards of the Environmental Protection Organization and can be used again.
