Wastewater Treatment Services in Kenya

Introduction

Kenya is one of the most developed countries in Africa with a rapidly growing economy. However, Kenya still faces basic challenges like environmental pollution from wastewater. Some of the major sources of wastewater are industrial effluent, domestic use, and agricultural activities, especially in large horticultural farms. To address these problems, an effective wastewater treatment system is required. This is why Watertech has invested heavily in providing world-class wastewater treatment services in Kenya. 

Why wastewater treatment services in Kenya are essential

The World Bank reports that barely half of Kenyans have access to clean water and only 40% of Nairobians are connected to the sewerage system. This makes many people to defecate in open spaces or water sources where they can spread potential epidemics like malaria or cholera. 

Apart from the above, industries also pollute water through industrial effluent like point source discharges where only one specific point within a wetland system may contain pollutants at any given time during periods when flows exceed those levels set out in permits issued by National Environmental Management Authority (NEMA). 

Wastewater treatment services include the removal of pollutants and impurities from wastewater to make it suitable for end use.

Water treatment companies in Kenya offer wastewater management services to industrial and commercial businesses that generate wastewater.

Wastewater treatment is a key component of wastewater management. Companies like Watertech that offer wastewater treatment services in Kenya are ideal for industrial, commercial, and government clients. At Watertech, we offer a comprehensive package that includes:

• Water quality monitoring and management.
• Industrial effluent recycling (for example, cooling towers).
• Oil spill clean-up using dispersants or biodegradable materials.

Two main reasons for treating wastewater.

The two main reasons for treating wastewater are:

1. To remove solids and hazardous substances before it can be discharged into public sewers or canals.
2. To treat wastewater so that it is safe to discharge into the environment.

Three most common forms of wastewater.

Wastewater is the liquid or semi-liquid residue that results from day-to-day water usage in different activities whether homes or businesses. It includes domestic sewage, industrial wastewater, and commercial sewage.

The most common form of wastewater is domestic sewage from toilets, showers, baths, and sinks. 

Industrial effluents include those from manufacturing processes such as paper mills; oil refineries; chemical plants; food processing plants (such as bakeries); clothing factories etc.

Commercial effluents come from restaurants, kiosks, hotels, etc., as well as other service industries such as cinemas where wastewater is generated during cleaning operations before patrons return home with their dinner plates in tow!

Toxic chemicals from industrial processes found in wastewater.

Wastewater may also contain toxic chemicals from industrial processes. Some of these chemicals cannot be removed by conventional treatment systems and must be managed on-site. For example, heavy metals such as lead and copper can build up in wastewater due to the corrosion of pipes or equipment used in industrial facilities. Heavy metals are also present in the effluent from many industries including mining and manufacturing operations.

Wastewater treatment plants remove most of these contaminants from treated water; however, some remain unaccounted for and must be disposed of at a waste site (e.g., a landfill).

Wastewater contains bacteria, fungi, and parasites.

Wastewater contains bacteria, fungi, and parasites that should be killed during primary treatment. 

Three main methods of treating wastewater in Kenya

Primary treatment involves the removal of suspended matter such as grit, oil, and grease. Secondary treatment involves the removal of dissolved organic matter such as fats and nitrogen compounds which can clog pipes or cause blockages in the sewer system, which could result in a blockage or back-up of water flow resulting in flooding in your premises. Tertiary treatment aims at disinfecting the water before discharge into sewers or rivers. 

Let’s look at each of these methods a little bit deeper below:

Primary treatment involves the removal of suspended matter such as grit, oil, and grease.

Primary treatment involves the removal of suspended matter such as grit, oil, and grease. It is the most basic form of wastewater treatment.

Primary treatment systems consist of a settling tank (or an open pond) into which wastewater flows. Wastewater is then pumped through screens or belts that remove large particles from the water, leaving smaller ones behind. This can be done using various techniques including gravity settling or centrifugal forces used in rotary clarifiers to separate solids from liquids.”

Secondary treatment involves the removal of dissolved organic matter such as fats and nitrogen compounds.

Secondary treatment involves the removal of dissolved organic matter such as fats and nitrogen compounds. This can be achieved by biological processes such as activated sludge or trickling filters. The goal of this process is to improve the quality of water before it is discharged into rivers or sewers

The secondary treatment system consists of two parts:

• A clarifier where suspended solids settle out, allowing clear water to enter the next stage in the process;
• A settling tank where settled solids cake on top, preventing further passage through later stages

Thirdly, we have tertiary treatment which aims at disinfecting the water before discharge into sewers or rivers.

Tertiary treatment involves the removal of dissolved organic matter such as fats and nitrogen compounds. This is done by using a biological process known as activated sludge.

The activated sludge is fed into an aeration tank where it grows microorganisms that consume the organics in the wastewater. The treated water is then discharged into sewers or rivers through pipes called diffusers.
