Effluent Treatment Plant

In the year 2018, Green City Water Technologies is a distinguished Manufacturer, Wholesaler and Trader offering an enormous consignment of Mild Steel Filter Press, Reverse Osmosis Plant etc.

One wastewater treatment technology type is the effluent treatment plant or ETP. Its objective is to release safe water into the environment by removing the harmful effects of wastewater and purifying industrial wastewater for reuse.

Depending on the industry, different materials can be found in industrial wastes. Some wastes contain grease and oil, while others contain hazardous substances (such as cyanide).

Degradable organic pollutants can be found in waste from factories that produce food and beverages. Due to the variety of pollutants found in industrial wastewater, special treatment technology called ETP is required.

The ETP plant treats wastewater from various industrial sectors including chemicals, pharmaceuticals, dyes, refineries, dairy, ready-mix plants, and textiles using various physical, chemical, biological, and membrane processes.

MBR is a process of Ultra filtration system in which semi permeable membranes are used to separate the solid and liquid form the good biological system through the way of after biological process (or) after clarified water use of clarifier process. The MBR is used to remove particulate and microbiological contaminates, but it does not remove the ions and small molecules, Membrane is fully submerged and comp active.

MBR system is to avoid the system of Conventional treatment methods like Clarifier, Sand filters like PSF&ACF and UF. And like conventional secondary treatment utilizes activated sludge, but place of gravity clarification the MBR employs a physical barrier in a form of a membrane for solid liquid separation. The membrane is constructed to serve as physical barrier, limiting the passage of suspended solids and colloidal materials while allowing clean effluent of Permeate to flow through, Since the MBR System does not rely on gravity separation, it can be operated at MLSS concentration up to 12 g/L in the membrane tank and also MBR is working without MLSS concentration like clarified water. The hollow fibre membrane is operation in outside to inside flow path with negative pressure and the micron is 0.03 µm.

Multiple Effect Evaporator

Multiple Effect Evaporator Principle It is a type of heat transfer equipment that uses natural convection or forced convection for the transfer of heat. Steam is used in the evaporator to heat up a solution containing a desired product. When the solution is heated, the water in it is converted into vapour, which is condensed. The vaporized concentrated solution is then removed or fed into a second evaporator for a further concentration process. Any solution that is concentrated using a single evaporator is called a single effect evaporator system, and any solution that is concentrated using more than one evaporator is called a multiple effect evaporator system. Multiple-effect evaporators use vapor from one evaporator to feed vapor to the steam chest of another evaporator. The heat from the initial steam is reused in successive effects in such a system.

These filters are normally used to remove suspended solid substances that cause turbidity from water. Their operation is very simple and consists in allowing water to pass through several layers of quartzite (sand) and, possibly, a layer of anthracite. The water passes through the filtering part, moving in the top-down direction, and during the process the substances retained on the first upper layer of sand increase filtration efficiency in the subsequent layers.

To clean the sand and thus regenerate the filter it is necessary to perform a backwash, whereby water (or water and air) passes through the filter from the bottom upwards, so that the backwash water will draw the previously filtered substances towards the point of discharge.

Industrial Reverse Osmosis Plant

Reverse Osmosis (RO) is a membrane-based process technology to purify water by separating the dissolved solids from feed stream resulting in permeate and reject stream for a wide range of applications in domestic as well as industrial applications. It is seen from literature review that RO technology is used to remove dissolved solids, colour, organic contaminants, and nitrate from feed stream. Hence RO technology used in the treatment of water and hazardous waste, separation processes in the food, beverage and paper industry, as well as recovery of organic and inorganic materials from chemical processes as an alternative method . This paper intends to provide an overall vision of RO technology as an alternative method for treating wastewater in different Industrial applications. The present short review shows applicability of RO system for treating effluents from beverage industry, distillery spent wash, ground water treatment, recovery of phenol compounds, and reclamation of wastewater and sea water reverse osmosis (SWRO) treatment indicating efficiency and applicability of RO technology.

screw press is used for sludge dewatering, using stainless steel as the Filtration method. Sludge is thickened and dewatered progressively inside the screw body with the movement of the moving rings, and ending by the fixed plate. The filtrate is drained from the gaps between fixed and moving rings and dewatered cake is discharged at the end plate, achieving a minimum solid content of 20%. Low speed rotation and special filtration design of the screw press make the machine a low consumption Energy with high yield automation unit, suitable for most projects and saving maintenance cost. The screw press also accepts a wide range of chemical and biological sludge industries including Municipal, Food & beverage, Papermaking, Dyeing, Printing and etc.

Sewage Treatment Plant

It might surprise you to know that we all drink and bathe in recycled water. The water we flush down the toilet is turned into potable water, and it is the job of sewage treatment plants to make this water fit for human consumption or release into rivers and oceans. Wastewater from sinks, baths, washing machines, toilets and other appliances has to go somewhere. After traversing miles of sewer network, it ends up in sewage treatment plants whose job is to treat and discharge it. Sewage treatment plants collect, treat, and discharge wastewater, providing a service essential to environmental and public health. Without adequate treatment, sewage will leach into the environment and contaminate ecosystems. For example, sewage contains bacteria and chemicals that break down using oxygen in the water. In doing so, they use oxygen that fish and aquatic life needs to survive, so it needs treatment to preserve the ecosystem. Returning sewage/wastewater to a specified quality for safe discharge is the most crucial role of the sewage treatment plant. Sewage treatment plants run wastewater through multiple treatment stages. After preliminary filtration, there are three main stages of wastewater treatment (primary, secondary, and tertiary), with the third stage reserved for polishing.
