How to reduce Cost in Dairy effluent with proper treatment?
Dairy industry has expanded in most nations due to increased demand for milk and milk products. This surge has resulted in the expansion of dairy industry. This industry's wastewater has high amounts of nutrients, chemical oxygen demand (COD), biological oxygen demand (BOD), total suspended solids (TSS), and organic and inorganic substances, which can create major environmental concerns if not adequately handled. Because of their high biodegradability, standard biological treatment procedures are appropriate for dairy wastewaters.
Long chain fatty acids produced during lipid hydrolysis, on the other hand, have inhibitory activity during anaerobic treatment. The most promising technique for the biological treatment of dairy wastewaters appears to be sequencing batch reactor (SBR) and up flow anaerobic sludge blanket (UASB) systems.
There is the use of aerobic and anaerobic treatment technologies for dairy sector effluent, although both treatment methods have drawbacks. The most pressing task is to develop cost-effective and ecologically friendly ways to water reuse and waste management. As a result, other treatment technologies including as coagulation, adsorption, membrane, and electrolysis procedures are being investigated as alternatives to biological treatment approaches.
A kilogram of dairy production needs between two and four litres of water to manufacture and can generate up to 20 litres of effluent depending on the product. As a result, dairy processors confront a variety of financial and long-term issues when it comes to industrial wastewater treatment. The nature of the trash, on the other hand, provides feasible options.The management of dairy industrial water is a critical issue for producers, particularly in terms of resource optimization and effluent volume reduction. Dairies must carefully assess their wastewater treatment systems as water utilities implement higher criteria for water released into sewers.
There are several industrial wastewater treatment methods available that are especially useful for the sort of wastewater produced by dairy businesses.
Anaerobic wastewater treatment systems, which employ anaerobic bacteria to convert organic contaminants or Chemical Oxygen Demand (COD) into biogas, are one example.
For example, an anaerobic membrane bioreactor that generates high-quality effluent that may be released directly to the sewer while maximizing renewable energy output by producing value biogas.
For dairies, it has the distinct benefit of having a remarkably compact footprint, allowing for the most efficient use of space. The created biogas may be utilized on-site to lower the need for fuel, steam, and power generation, resulting in cost savings. To cut expenses even further, wastewater may be treated and utilized for applications such as Cleaning in Place (CIP) operations.
Reverse osmosis (RO) technology, for example, employs a membrane to remove 99 percent of residual COD, dissolved salts, and bacteria from treated industrial wastewater. This technique is so effective that it can create water that is as good as or better than the mains supply. Pressure drives the reverse osmosis process, and the low-pressure membranes and high-efficiency pumps make it one of the most energy-efficient systems in the market, reducing both carbon emissions and operational costs.
