Consulting to apply biogas cellar using composit material
Experiencing long periods of model development to build organic waste silo and generate heat source serving households, most households chose to build silos with cement and bricks. Through several researches which were applied in Vietnam, we would point out the advantages and disadvantages of the two types of silo built with cement and composites used for customer to choose with advanced technology and cheapest cost.
Advantages and disadvantages of biogas composite with brick basement
BIOGAS with Brick
|– Installation rapidly- Check the tightness immediately after installation||– It takes a few days.- Do not check the tightness immediately after installation|
|Durability. Able to withstand mechanical action and chemical. Should be installed in place of soft soil, soil subsidence including the pebble stone, contaminated areas, acid sulphate soils, …||Easy to subsidence, cracking, prone to air leaks out did not fix. Susceptible to acid corrosion of concrete surfaces, gas detectors make stew out|
|– High pressure biogas up to 1.6 mH2O and pressurization automatic;- When there is too much biogas, the tank exhaust through two pressurized column. Needless safety valve||– Normal tank is usually only 0.8 mH2O pressure biogas;- Must have safety valves or exhaust pipe automatic redundancy|
|– Very easy to remove residue (about 4 -5 years / time) from pressurized tank width columns.||– Difficult to remove the residue (about 4 -5 years / times) from cellar. Because it must be removed the collar button to interrupt the process of using biogas|
|Installed, a user can dig up the time to move to another place||easily cellar brick can not do this|
Therefore composite biogas tanks which are quick installed, durable, lightweight, portable, closed, acid resistant, quick to obtain biogas, produce more biogas than brick cellar, automatically breaks scum and pushes out guano from the tanks … are the best choice for the biogas tank.
