Environmental Impact
Mining & Quarry Waste Water
Mining wastewater can harm the ecosystem, making proper treatment essential before its release into the environment.
Untreated water from mining activities poses significant environmental risks, primarily due to the release of heavy metals and other toxic substances. These pollutants can contaminate nearby water bodies, harming aquatic ecosystems and potentially spreading through the food chain.
why need to treat?
Common Contaminants Found in Mining Wastewater
Mining activities often generate significant volumes of wastewater that contain a variety of contaminants. These pollutants arise from ore extraction, mineral processing, and tailings disposal.
The most common contaminants in mining wastewater include:
1. Heavy Metals: Metals such as arsenic, lead, mercury, cadmium, and chromium.
2. Acid Mine Drainage (AMD)
3. Suspended Solids
How To treat?
Treatment Methods for Mining & Quarry Wastewater
1. Water Recycling & ZERO Liquid Discharge (ZLD) System (Re-use water for mining activities)
2. Specialty Coagulants & Flocculants for Mining Waste
3. Filtration System & Ion Exchange
Effluent Discharge Standards
Effluent Discharge Parameters under this regulation:
pH Level: The pH of the effluent 6-9 . This range is important because if the water is too acidic or too alkaline, it can harm aquatic life and the surrounding environment.
Suspended Solids: High levels of suspended solids can clog waterways and harm aquatic organisms.
Chemical Oxygen Demand (COD): This measures the amount of oxygen required to break down organic matter in the water. High COD levels indicate pollution from organic waste, which can affect water quality.
Biochemical Oxygen Demand (BOD): High BOD means there’s a lot of biodegradable material, which can deplete oxygen in water, harming fish and other aquatic life.
Oil and Grease: The discharge of oil and grease must be minimal. These substances can pollute water bodies and cause harm to ecosystems.
Heavy Metals: Effluents should not contain high concentrations of harmful metals like lead, mercury, and arsenic. These are toxic and can accumulate in the food chain, posing risks to health and the environment.
