Pharmaceutical & Bulk Drug

Water plays a critical role in the pharmaceutical industry, particularly in the manufacturing of antibiotics and other drugs. Wastewater generation in this sector primarily results from process water used in manufacturing, R&D laboratories, floor wash, cooling tower and boiler blow down, and occasionally condenser waste from evaporation. This wastewater can contain high levels of dissolved solids, suspended solids, and significant amounts of organic and biological matter.

KEP Engineering has successfully delivered tailored solutions to clients in the pharmaceutical sector, focusing on the recovery of valuable solvents and efficient water treatment. Wastewater generation in this sector primarily results from process water used in manufacturing, R&D laboratories, floor washing, cooling towers, and boiler blowdown, and occasionally from condenser waste generated during evaporation.

Automobile

The Indian automobile industry is one of the largest and fastest-growing in the world, making significant contributions to the country's economy. As the industry progresses, production capacities are expanding, leading to a substantial increase in wastewater generation alongside a rising demand for fresh water. This requirement can be mitigated through effective water treatment, recycling, and reuse techniques. Automotive manufacturing utilises water throughout production, from cleaning and metal forming to painting and testing, which can contain contaminants like zinc (Zn), nickel (Ni), and phosphorus (P). This waste typically has TSS less than 1,000 mg/L, varying total dissolved solids (TDS) levels, some acid traces, and fluctuating pH levels.

At KEP Engineering, we are dedicated to providing innovative solutions that enhance water management in the automobile sector. Our advanced technologies focus on wastewater treatment and resource recovery, enabling manufacturers to minimize their environmental impact while optimizing their water usage. By implementing our systems, clients have significantly reduced their dependence on fresh water and improved sustainability in their operations.

Food & Beverages

In food processing applications, water is used as an ingredient and as a source for initial and intermediate cleaning. As a result of this extensive water use, the food industry's primary concern is to ensure that water and wastewater are handled in the most cost-effective manner and reused wherever possible to reduce costs and remain environmentally compliant.

KEP offers a comprehensive selection of wastewater equipment and technologies that solve the challenges posed by fats, proteins, and carbohydrates in the Food and Beverage industry. The main characteristics of wastewater in this industry are high levels of sugar and alcohol, low pH levels, average COD and BOD values over 5,000 mg/L and 3,000 mg/L, respectively, and total suspended solids over 1,800 mg/L. This requires pretreatment, membrane filtration, and removal of dissolved solids. KEP has the expertise and treatment technologies to not only ensure compliance but also enhance your overall environmental performance.

Solar

The solar industry, while known for its renewable energy benefits, also generates wastewater during the manufacturing process of solar panels. It faces challenges related to wastewater management, as this wastewater can contain pollutants like heavy metals and solvents. KEP's MVRE technology offers an effective solution by enhancing water recovery and reducing steam requirements. This innovative approach recycles water efficiently, minimising overall consumption and wastewater output, while lowering energy costs and environmental impact.

Chemical & Agro-chemicals

The challenges associated with wastewater generated in the chemical industry are significant and require effective treatment methods. This wastewater often contains highly reactive, corrosive, and concentrated chemicals, as well as valuable components that need to be recovered. Similarly, the agro-chemical industry, which relies on water for the production of fertilisers and agricultural products, generates substantial amounts of wastewater. Effective treatment of this chemical-laden wastewater must consider various parameters, including pH levels and the concentration of different components present.

At KEP, we offer a comprehensive range of treatment technologies, including physico-chemical processes, biological treatment, membrane separation, and thermal systems (such as evaporators and crystallisers/dryers). Each application is meticulously evaluated from a techno-economic perspective to address diverse and complex treatment requirements and to identify the most suitable technology options.

Textile

The textile industry is one of the largest consumers of water, generating wastewater containing dyes, starches, surfactants, and heavy metals. The wastewater is typically high in BOD, COD, and suspended solids, requiring specialised treatment to meet discharge standards.

We, at KEP Engineering, offer integrated solutions for textile wastewater, including biological treatment, reverse osmosis, and complete ZLD systems. Our solutions enhance water recycling, reduce sludge generation, and improve overall sustainability for textile manufacturers.

Dyes & Paints

The dyes and paints industry produces wastewater containing synthetic dyes, heavy metals, solvents, and other hazardous chemicals. This wastewater is highly coloured, has fluctuating pH levels, and carries a high organic load, posing significant treatment challenges.

KEP Engineering specialises in membrane filtration and coagulation-flocculation techniques to effectively treat this wastewater. Our solutions ensure the removal of toxic components, colour, and odour while recovering valuable by-products for reuse.

Leather & Tannery

The leather and tannery industry generates wastewater with high levels of organic matter, chromium, sulfides, and other toxic chemicals due to processes such as soaking, liming, tanning, and dyeing. This wastewater is characterised by high BOD, COD, and TDS, making it challenging to treat.

KEP Engineering provides a variety of best-fit solutions for the leather industry, focusing on chromium recovery, sulfide removal, and advanced biological treatment systems. Our technologies ensure compliance with environmental regulations while enabling water reuse and reducing operational costs.

Oil & Gas

Wastewater generation in the oil and gas industry is a significant concern due to various processes that produce large volumes of contaminated water. The primary source is produced water, which arises from the extraction of oil and gas and often contains hydrocarbons, salts, heavy metals, and other chemicals. Additionally, drilling activities and refining processes contribute to cooling and process water laden with oils and solvents. This wastewater typically has high salinity, hydrocarbon contamination, and potentially toxic chemicals.

To effectively treat this wastewater, pretreatment to remove oil and grease is the primary step, followed by reducing its organic load using advanced technologies such as MEE and MVRE.
