Ecological information - waste treatment
Spilled sodium water glass should be mixed with sand in order to consolidate. The mass should be mixed with H2SO4 to the neutral pH level. During neutralization silica becomes a jelly-like mixture. Precipitate silica should be put to containers and recycled in the way indicated by local office of environment protection.
