Water and Wastewater Treatment
KERASIEV® Ceramic Membranes provide efficient filtration for water and wastewater treatment across industries. Their resistance to chemicals and fouling makes them ideal for Zero Liquid Discharge (ZLD) systems, water recycling, and effluent treatment, contributing to water conservation and reducing environmental impact.
Seawater RO pre-treatment
MF Ceramic membrane is a competitive pre-treatment process for desalination using RO in terms of its higher flux and more stable operation characteristics than common organic/polymer membrane systems. The objective of pre-treatment before reverse osmosis (RO) membranes is to remove undesirable and particulate fouling materials (algae, suspended and colloidal particles).
Dairy
Membrane technology has revolutionized the dairy sector. Different types of membranes are used in the industry for various purposes like extending the shelf life of milk without exposure to heat treatment, standardization of the major components of milk for tailoring new products as well increasing yield and quality of the dairy products, and concentrating, fractionation and purification of milk components especially valuable milk proteins in their natural state. In the cheese industry, membranes increase the yield and quality of cheese and control the whey volume, by concentrating the cheese milk. The membrane separation techniques utilized in the dairy industry serve different purposes: UF – typically used for concentration of milk proteins in milk and whey and for protein standardization of milk intended for cheese, yoghurt and other products, but it is also used for clarification of fruit- and berry-juices MF – mostly used for reduction of bacteria in skimmed milk, whey and brine, but also for defatting whey intended for whey protein concentrate (WPC) and for protein fractionation Ceramic membranes is steadily gaining ground in the dairy industry, especially in systems for the reduction of bacteria in milk, whey, WPC and brine
Distillery & Sugar
Ceramic Membrane Technology in Distillery and Beverage Industries
Internationally, ceramic membrane filters have long been used in beverage filtration, including beer. In recent years, the wine industry has widely adopted cross-flow filtration with ceramic membranes, offering over 10 years of membrane life. This technology is now an accepted process in the wine and cider industries.
In India’s distillery sector, wastewater from the distillation column, known as spent wash liquor, contains high levels of suspended solids, dissolved impurities, organic matter, color, TDS, and oils. Due to the high impurity load, conventional wastewater treatment plants struggle to meet pollution control board limits. This is where ceramic membrane technology offers a solution.
Spent wash liquor can first pass through a digester to convert organic load into biogas, which is used for steam and power generation. It is then treated by a membrane system to produce purified water. Alternatively, it can undergo pre-filtration followed by membrane treatment, bypassing traditional primary and secondary treatment processes. The membrane system effectively separates pure water, which can be recycled back into the process, while the membrane reject can be further concentrated using thermal energy and directly used as biofuel.
Additionally, during beer production, prior to distillation, the fermentation solution should be passed through a membrane system. This filtration removes suspended solids and high molecular weight dissolved impurities, enhancing the efficiency of the distillery column by improving heat transfer and reducing maintenance needs. Furthermore, this reduces the operational costs of effluent treatment plants.
By saving energy in distillery operations, ceramic membrane technology also contributes to a reduction in CO2 emissions, helping mitigate ozone layer depletion and improving environmental sustainability.
Textile
KERASIEV Ceramic Membranes by Need Inovation provide an advanced solution for treating textile effluents, effectively removing dyes, suspended solids, and pollutants. Made using sol-gel technology, these membranes offer superior filtration, resistance to fouling, and durability, outperforming traditional polymer membranes. With high chemical and thermal stability, KERASIEV Membranes ensure long-term, cost-effective performance in harsh conditions. Ideal for textile manufacturing, dyeing, and water recycling, they support sustainable practices by enabling water reuse, reducing environmental impact, and complying with discharge regulations.
