The Ultimate FAQ Guide for Liquid Waste Disposal.

Virtually all domestic, commercial or industrial processes generate highly polluted liquid waste. To protect the ecosystem and its inhabitants from the volatile pollutants in the liquid waste, treatment or appropriate disposal is mandatory. Environmental protection agencies and local governments have consequently enacted stringent laws on effluent quality and disposal methods.

The emergence of modern wastewater management technologies such as wastewater treatment has provided alternative solutions to the devastating liquid waste menace. Underneath, we are going to walk through the appropriate liquid waste disposal methods, the required machinery, and alternatives to wastewater disposal.

➣ What is Liquid Waste Disposal?

Liquid waste simply refers to fluid refuse drawn from commercial enterprises, residential complexes, or industries. Liquid waste or wastewater often harbors aggressive impurities, which pose a threat to the environment and surrounding human life. Liquid waste disposal on the other hand refers to the process of discarding the liquid waste. At present, liquid waste disposal is heavily regulated as the relevant authorities intensify attempts to curb environmental degradation.

There are varying liquid waste disposal methods approved by environmental protection agencies but the liquid waste must first meet the quality threshold. Wastewater treatment is now common practice prior to disposal. The availability of first-rate wastewater treatment machinery has positively impacted liquid waste disposal. It is now possible to re-inject liquid waste into water bodies without threatening to pollute the water bodies.

Liquid waste treatment also opens up the possibility of reusing or recycling wastewater. This is particularly important given that potable water is insufficient and inaccessible in certain regions. The recycled wastewater can be utilized in applications such as agricultural irrigation, concrete mixing, and cooling of power plants.

➣ What Are The Commonly Utilized Liquid Waste Disposal Methods?

Owing to the threat posed by liquid waste on the ecosystem and its inhabitants, liquid waste disposal is presently, stringently regulated. The appropriate disposal method depends on the characterization of your liquid waste-the contaminants present and their concentration. Underneath, we will briefly look at the most utilized liquid waste disposal techniques.

●       Composting.

Composting is an environmentally friendly, inexpensive, and uncomplicated liquid waste disposal process that converts liquid waste into compost. This method is mainly suited to non-hazardous effluent. The water in the effluent is extracted using technologies such as evaporation while the resulting residue of organic compounds is used to produce organic fertilizer.

●       Dewatering.

Dewatering alienates the water in the liquid waste from the harbored solids. The fluid refuse is technically pumped into a sturdy bag, which extracts the water to generate solid waste, which can be discarded in a landfill. The extracted water is appropriately treated using filtration or other technologies.

●       Incineration.

In the incineration process, hazardous components in the liquid waste are extracted through combustion. Distinct furnaces such as multiple-hearth and fluidized-bed furnaces provide heat that eliminates contaminants such as acids and oils. However, it is not always advisable to use incineration as a disposal technique given that it discharges greenhouse gasses and toxic impurities into the ecosystem. Here is an illustration of liquid waste incineration.

●       Sedimentation.

Sedimentation seeks to separate the liquid waste from the dissolved or suspended solids just like dewatering. It however depends on gravitational forces rather than centrifugal forces. The solid constituents settle at the bottom of the sedimentation basin making it easy to separate them from the liquid waste. The resulting liquid can be treated before disposal while the suspended solids are disposed of in landfills.

●       Discarding.

Alternatively, you can dispose of the liquid waste without treating or modifying it as long as you are in compliance with waste disposal laws. You can seek the aid of accredited waste management firms. This method is often used by enterprises reluctant to invest in liquid waste treatment systems.

●       Solidification.

This disposal technique converts the liquid waste into a compact and rigid solid using binding agents. Quite often, solidification is integrated with stabilization to minimize or prevent the leakage of lethal impurities into the environment.  Some of the most utilized binding agents include gypsum, lime ash, phosphate, and cement kiln dust.

➣ Which Technologies Can Be Used to Treat Liquid Waste Before Disposal?

Liquid waste typically harbors varying impurities, some of which are capable of harming the environment and pose a serious threat to public health. In addition, liquid waste disposal regulations dictate the quality of effluent to be discharged. Failure to comply with these regulations can attract heavy fines. The following are some widely exploited wastewater treatment technologies.

●       Advanced oxidation.

Oxidation is a technology that involves the movement of electrons between two substances. This transfer of electrons leads to a normalized hydrogen electrode. Advanced oxidation is a widely utilized liquid waste treatment technology that primarily extracts elevated chemical oxygen demand (COD) levels. This technology is mainly employed after the liquid waste has been bio-treated.

●       Activated sludge treatment.

Activated sludge treatment is inarguably the most utilized biological wastewater treatment technique. The process utilizes microorganisms, which are powered by oxygen to digest biodegradable organics in the liquid waste. Essentially, oxygen is introduced in the incoming liquid waste to inspire the propagation of bacteria.

The removal efficiency of activated sludge treatment often hinges on the hydraulic residence time, temperature, influent load, and oxygen supply. Underneath is a quick video to help you understand the activated sludge process.

●       Reverse osmosis.

Liquid waste can also be treated using reverse osmosis to shrink the concentration of dissolved solids, harmful microorganisms, dissolved ions, organic chemicals, and heavy metals. Reverse osmosis relies on pressure to force the alienation of impurities from water using partially porous membranes. This technology is most effective when deployed in the post-treatment or polishing stage.

●       Membrane bioreactor (MBR) treatment.

Membrane bioreactor treatment is a contemporary technology that elevates the effectiveness and efficiency of biological treatment by supplementing it with membrane filtration. MBR eliminates both organic compounds and suspended matter from liquid waste using bio-treatment and ultrafiltration. The membrane filtration systems used in membrane bioreactor treatment use semipermeable membranes with porosities ranging from 0.05-0.4 µm.
