Liquid waste disposal and septic tank services for households, businesses, and industries in Australia

 Liquid waste can contain a variety of harmful and toxic ingredients, like fats, oil, and grease (FOG), used oil, and sludge, that pose a threat to human health and the environment. It is produced by households and also through manufacturing processes. Households generate a variety of wastewater, like grey water from bathing and kitchen, backwater from toilets, and combined water, which is a mixture of grey and backwater. Sewerage contains grey and black water from households in the presence or absence of a septic tank. The septic tank acts as a sedimentation and digestion chamber, allowing settleable solids to sink to the bottom over a retention time of one to two days. Sewage contains wastewater from households, commercial establishments, and industries.  

 

Sewage water contains harmful bacteria and germs, and also the organic matter that decomposes, and gives it a bad odour. It can be treated professionally and in a safe way by experts, such as the ones available with Clarence Valley Septics, that serves Lismore, Ballina, Byron, Kyogle, Grafton, and Coffs Harbour council areas. Sewage water can be treated through three treatment methods:  

 

Primary Treatment: This process of liquid waste disposal mechanically removes solid materials in the wastewater with the use of grit chambers, sedimentation, and metal screening. Grit chamber allows for settlement of heavier solids, such as sand, into the bottom while metal screening removes large floating objects, like rags and masses of waste.  

 

Secondary Treatment: A filter method or sludge process is used by the liquid waste disposal service in this liquid waste treatment method for biological oxidation of organic matter. In filter method, wastewater is sprinkled on a bed of small stones one to two metres deep that results in the growth of algae and fungi, and the wastewater gets oxidised. In the sludge process, liquid from the sedimentation tank is mixed with activated sludge which is rich in aerobic bacteria, and then subjected to aeration. This way, waste liquid gets oxidised into carbon dioxide, water, and nutrients.   

Tertiary Treatment:The residue from the primary and secondary treatment methods may still have some suspended solids and toxic metal compounds which are removed by liquid waste disposal services with tertiary methods like reverse osmosis. Chlorination is performed in the end to remove disease-causing bacteria and other germs from wastewater.

Chemical-free treatment of septic tank 

  

When wastewater from the household reaches the septic tank, its design makes the wastewater split. Sludge or heavy particulate sink to the bottom while oils, fats, and proteins make a floating scum layer above. The relatively transparent layer, known as affluent or grey water, remains at the centre. The combination of all three ingredients of a septic tank is known as septage. Only effluent from the septic tank is discharged into the drain area, or leach field, of the septic tank. Septic tank services by Clarence Valley Septics make use of biological decomposition, settlement, and drainage, without making use of any chemicals.  

 

Removing sludge and solids from septic tank   

To remove sludge and solids from the septic tank, regular cleaning is required. However, the frequency of septic tank service would depend on its use and size, and may be needed every one to three years. As a preventive measure, a septic tank should be inspected every year for blockage and damage.  Inspection by septic tank service would include measuring sludge and scrum quantities, inspection of the pipes and structures, and inspection of the drain field. Regular emptying will prevent pollution of nearby streams, and also the risk of solids escaping the tank and damaging the clarified liquid.    

High-pressure jetting for quick and efficient cleaning   

High-pressure water jetting may be used to clean the tank, its pipes, and grease traps, quickly and efficiently. The septic tank is pumped out before jetting, eductor trucks are normally used by septic tank services to transport bulk water from septic tank cleaning. The trucks are equipped with a high-pressure gun for hydro excavation, and washing down pits. Septic Tank Services by Clarence Valley Septics will save you thousands of dollars in costly repairs if the tank is blocked, or gets damaged.
