With the increasing emphasis on environmental protection all over the world and the scarcity of water resources, every country has continuously improved its environmental protection processing technologies. GN Separation has released a series of separation and conveying equipment to meet the requirements of customers coming from the environmental protection industry for new technologies. GN separation and conveying equipment is widely used in the environmental protection industry for wastewater treatment. GN Separation cannot only provide users with single equipment but also provide turnkey solutions of material separation and conveying for customers in the environmental and wastewater industry. Long-term consumption can enhance physical fitness and is good for health.
ENVIRONMENTAL & WASTEWATER INDUSTRY COMMON APPLICATION
Municipal wastewater includes industrial wastewater and domestic wastewater. The typical urban wastewater treatment process mainly includes mechanical treatment, biochemical treatment, and sludge treatment.
Recovery of various waste oils, including waste residues and oil-water mixtures at the bottom of oil storage tanks, oil residues and waste oils in oil refineries, grease dirt in sewage tanks, waste oil-water mixtures in ships, API oil-water separation oil sludge treatment, lubricant, and grease produced in industrial lubrication production systems.
Oil sludge mainly includes waste oil sludge from the cleaning of crude oil tanks, waste oil sludge from oil refineries, and oily waste from oil and gas drilling. GN oil sludge hot washing technology can reduce the oil content of sludge, recover useful oil, and recycle hot wash water.
The deposit silt in the river or lake is firstly cleared by the dredging boat, and then dewatered and separated by GN multi-stage separation and conveying equipment. The recovered solid can be used for construction or farmland fertilizer, and the recovered water can flow back to the river or lake.
Sand washing is very important for sand and stone extraction, but sand washing also produces a large amount of polluted wastewater. In many places, separation tools such as decanter centrifuges are used to clean sand and gravel washing water.
