Pretreatment Plant
The feed water, depending on its source, may contain various concentrations of suspended solids and dissolved matter. Suspended solids may consist of inorganic particles, colloids and biological debris such as microorganisms and algae. Dissolved matter may consists of highly soluble salts, such as chlorides, and sparingly soluble salts, such as carbonates, sulfates, and silica. The objective of the feed water pretreatment process is to improve the quality of the feed water to the level which would result in reliable operation. Marcuras provides following processes to make feed water suitable for the downstream processes:
Clarifiers
Our innovative and advanced water pretreatment system involves usage of various water clarifiers. Our range of water clarifiers includes water pretreatment plant, lamella clarifiers, tube settlers, clarifiers & flocculators, high rate solids contact clarifiers (HRSCC), inclined plate clarifier, side stream filters, etc.
Clarifiers & Flocculators
Our company is involved in manufacturing and exporting a wide range of Clarifiers & Flocculators. Flocculators are used for waste or surface water clarification, to optimize particles coagulation and flocculation. It is one of the most popular and proven processes used to treat contaminants for removal in water and wastewater. While some systems settle solids out of the liquid stream by gravity, others use flotation methods to float the solids to the top to be skimmed away.
High Rate Solids Contact Clarifier
High Rate Solids Contact Clarifiers (HRSCC) are next generation technologies that achieve higher throughput in a smaller footprint than conventional clarifiers - resulting in cost savings and improved performance.
The design features of the solids contact type clarifier provide the three zones necessary for proper clarification:
Rapid mix zone, where raw water, recirculated precipitates and fresh reagents are rapidly mixed together.
Slow mix zone, where gentle mixing permits floc formation and brings the floc into intimate contact with the suspended impurities.
Clarification or settling cone, where the upward flow (rise rate) is reduced to a low value to permit the precipitation to settle out.
This ensures a higher clarified water quality and greater tolerance to variations in inlet conditions. Our company is involved in producing HRSCC, which is very reliable and cost-effective.
Tube Settler / Lamella Clarifiers
We are engaged in manufacturing and supplying Inclined plate (lamella) clarifiers, tube settler, which are based on innovative technologies that increase basin settling area by creating an inclined settling surface. Overall plant footprint can be reduced by up to 90% using these technologies. These product are used for clarification of water and other liquids from suspended and colloidal particles.
Filtration System
A water filter removes impurities from water by means of a fine physical barrier, a chemical process or a biological process. We offer a wide range of water filtration systems that provide you clean & healthy water to use. Designed to meet the stringent requirements of clients these include. The entire ranges of filter are available in different MOC like FRP, MS, MSRL etc. They are available fully automatic, remotely operated, manually operated or with multiport valves.
Activated Carbon Filter
The principal media in these filters is activated carbon. Other supporting media include pebbles of various sizes, crushed gravel and silex. The activated carbon is a highly porous media. This property of carbon allows it to adsorb the free chlorine in raw water. Also organic matter present in colloidal form is adsorbed in these pores. Thus odour emanating from raw water on account of these colloids is reduced. The activated carbon present in the standard range has an iodine value of 450. This carbon is also available in iodine values of 600, 900 and 1200.
Iron Removal Filter
The principal media in these filters is manganese dioxide. Other supporting media include pebbles of various sizes, crushed gravel and silex. Manganese dioxide catalyses precipitation of iron and holds back the precipitated matter on the filter bed. Also manganese dioxide acts as a strong oxidizing agent.
Dual Media Filter / Sand Filter
Our filters work on the principal of depth filtration. The principal media in these filters is quartz grade sand and anthracite. Other supporting media include pebbles of various sizes, crushed gravel and silex. The major advantage of this kind of filters is that anthracite which provides for coarse filtration is lighter than filtering sand. Due to which one stage of coarse filtration takes place on the anthracite bed and the next stage takes place on the sand bed. Thus, depth filtration is achieved. Since both media (viz sand and anthracite) are employed their capacities the dirt loading capacity of these filters is twice that of pressure sand filters. Hence these type of filters are more capable and gave high performance.
