Rainwater Harvesting Kerry
A rainwater tank is the key aspect of rainwater harvesting system. However, you must consider the various components in the system so that the water quality does not get affected. Thus, identify the important components of rainwater harvesting system before planning to install one.
Remember, the components which are listed below can be of a good quality only if you purchase the rainwater harvesting sytem from a reputed supplier of water treatment systems in Cork.
Gutter Guard Screening
Invest in gutter screens if your home surrounding is prone to bush and trees. It might be a good idea to prevent leaves and debris from building up and blocking the gutters. Free flow of rainwater is obvious.
Rain Head/Leaf Eater
Rain heads are also known as leaf eaters. They deflect leaves and debris to prevent their entry into the pipes that carry water. They are installed just below the gutter downpipe, at the top of the pipework that directs rainwater into the tank.
It is important to install tank screening to prevent mosquitoes, insects and debris from finding their way into the tank. This screening is installed on top of the tank.
Installing water diverters is a good idea when your tank water is distributed in the home. When it rains for the first time, it often contains dust and debris. Thus, to divert and flush this dirty water away from the tank, water diverters are a good component.
When choosing rainwater storage, first determine the requirement of water in your house and the storage capacity on the roof. Identify an appropriate site in your property to install the water tank, or you can also opt for multiple short storages.
Rainwater tanks have a hole at the top to let out the excess water through a piping connected with it. It is important to divert the water away from the building and other structures to avoid forming moss and damaging them. It is a good idea to design your garden effectively to soak up excess rainwater or install a separate stormwater detention tank where excess rainwater can be stored.
Pump and Filtration
To use tank water throughout the property, a pump is a vital installation. Filtration should also be installed, especially if the water is used for drinking or cooking purpose.
It is important to know about these important components while you are using rainwater. To ensure safe water flow throughout the building, it is recommend to install a rainwater harvesting system from reputed water treatment systems in Cork.
Sewage treatment involves removal of contaminants and harmful elements from waste water, which is primarily discharged from households. Industrially viable waste water is produced by removal of contaminants through biological, physical and chemical processes.
Sewage, generally speaking, refers to waste water from household toilets, showers, baths, kitchens and sinks that drain into the sewers. Industrial liquid waste from power plants and refineries can also be termed as sewage. Industrial sewage differs from household sewage in its content. Industrial sewage often contains waste that is harmful to the environment if left untreated, whereas household sewage would cause general accumulation of waste water that leads to mosquitoes breeding, which in turn, can bring forth a plethora of diseases.
The most basic aim of any water treatment plant is to produce an affluent which causes as little harm as possible when released into the environment, hence reducing pollution caused by releasing untreated waste water into the surrounding environment.
Pretreatment is used to remove all substances from the sewage that may clog or damage the sewage carrying lines. This is done automatically by a mechanical screen bar in modern plants that serve big populations. The solid waste collected is either incinerated or disposed off in landfills.
Sewage treatment involves three main stages:
Primary treatment: This involves temporarily storing the sewage in a sedimentation basin where the solids can settle down to the bottom while fluids such as grease, oil and lighter solids float up to the surface. This separation allows floating and settled materials to be removed and the liquid can be either discharged or sent for secondary treatment.
Secondary treatment: This process removes suspended and dissolved organic matter. It is performed by indigenous micro-organisms in a controlled environment. Secondary treatment may require a step to separate the micro-organisms from the treated water before discharge or further treatment.
Tertiary treatment: This step is performed only when the water is to be discharged into a fragile or sensitive ecosystem like an estuary, low flow river or coral reef. Water is either disinfected physically or chemically using lagoons or microfiltration before discharging it into any water body like a river, stream or bay.
Odors emitted by a sewage plant are an indication of an anaerobic or septic environment. Early stages are more likely to produce foul smelling gases such as hydrogen sulphide. If the plant is near an urban area, then carbon reactors are used to treat the odours.
A conventional water treatment plant in Cork uses 30% of its annual operating cost on energy requirements. The requirements vary with type of treatment plant. For example, plants near wetlands have lower energy requirement than plants near urban areas because cost of transportation of water through pumps to water bodies is reduced. Similarly, treatment plants that produce biogas from anaerobic digestion can meet all their energy requirements in-house.
