A papermaking process with maintained retention and improved formation is provided. The papermaking process includes the step of adding bentonite to the white water prior to the exposure of the white water to the shear stages of the papermaking system. The bentonite may be added anywhere from the white water silo up to the introduction of the white water to the fan pump. The flocculant may also be added to the white water with or shortly after the addition of the bentonite or a split feed of flocculant may be provided whereby some of the flocculant is added to the white water and an additional portion of flocculant is added to the thin stock prior to the entry of the thin stock into the header box.
